Figurel is a horizontal sectional view Figure i is another transverse sectional view', talren on the line 4-i ot Figure lV and looking in thedirection ot the arrows.

The presentinvention is designed tor'nsev in exactlyl the same manner Vas that4 disclosed in the aforesaid Patent No. 1,409,002, where-A in'is shown a tractorhaving a divided axle, each axle. being composed ot' two parts, having separatemeans tor connectingor dis connecting the said two Aparts of each aide, and requiring' two operations to arrange the parts 'for actuation through the power-A driven ditierential todrive the machine Vtor.- ward for pulling` or hauiing in the usual manner, and a separate and distinct opera-y tion tor throwing` 'into or out of gear, the drum winding mechani'smincorporated therein. The present-inventionA requires only one operation toy arrange the parts of the separate a'Xles to apply the power tothe traction wheels tor'inoving the vehicle bodily inV either direction, a' reverse action causing the same to standstill, at either ot which times theA winding means may lbe operated tor winding in on a1 cable to litt well-drills, casings, etc., out Vot wells, ,and similar hoistF ing operations, or-tor'the operation ot a helt'or'sproclret chain for; running machines of digerentekinds;y

Reterringato;thedrawings there is shown, in Figure l, the rear portion oic al weli- 1Known type oi tractor, including the tubular CII said flanges being suitably apertured at regular intervals and preferably formed integrally with the ring.

At one side, preferably the left, the aforesaid ring 2 is adapted to support a hollow, tap-ered axle housing` 11, extending outwardly therefrom and having its inner end flared outwardly, `as indicated at 5, and terminating in an attachment flange having suitable spaced apertures for the reception of bolts 6 for the purpose of securing the same to the adjacent flange 3. rhe rear side of the tapered axle housing d is formed straight, as indicated at 7, for the purpose of providing space for the flanges ol a winding drum to be later described. r1`he axle housing` 4 is provid-ed atits outer end, with a seat S, for the' reception of' the usual roller bearings 9 to reduce the friction of the left hand axle or" the tractor'.

At the right hand side, the ring 2 is adapted to support an additional housing 10 which is circular in form and provided on its outer end with an inturned annular flange 11, while the inn-er end is also provided with a similar flange, suitably apertured, for the reception of fastening bolts 12 to hold the housing in place on the frame of the machine.

The housing is provided with a rearwardly-extending oft-set 13 formed integrally therewith and arranged at an angle to the housing 10, as clearly shown in Figures Q and 3 of the drawings. At the outer or right hand side, the extension 18 is provided with a semi-circular bearing 1st, while the inner, or left hand wall of the extension 13 is extended outwardly and formed into a semicircular bearing 15. A cap or cover 1G is adapted to be secured to the open end of the extension, the co-acting faces of the two parts being suitably flanged for the reception of bolts in the usual manner, and the cover 16 being provided with complementary bearings 17 and 18 for co-action with the bearings formed in the extension 13.

The right hand axle housing 19 is of tubular form and is provided, at its inner end, with. an attaching plate 2O of the same diameter' as the diameter of the aforesaid housing 10, the said plate having suitable apertures adjacent to its periphery for the reception of bolts 21, which secure the plate in position to the aforesaid flange 11 to form a removable closure or head for the housing 10.

The head 2O is provided on its inn-er face with an annular enlargement 22 and on the outer face with a similar enlargement 23, the latter being integrally connected to the aforesaid axle housing 19 on the right hand side of the machine and being of greater diameter than the same. The inner enlargement 22 is reduced throughout the greater portion of' its length to provide an inwardneaaeoe ly-extending sleeve Q4, the inner end being open and the outer end of the bore thereof extending into said outer enlargement 23. All of the part-s as hereinbefore described, form the frame or supporting means and housing means for the various active parts of the invention as hereinafter described.

The. left hand axlehousing 4 is provided, near its out-er, free end, 'with a rearwardly and upwardly extending arm 25, preferably formed integrally therewith, and another, similar arm 26. is joined to the said axle housing where the latter flares out at 5 and is joined to the ring 2. In like manner the axle housing 19 carries a third arm 27 extending in the same direction, the said arms being suitably flanged or ribbed to provide the necessary strength, and having at their free ends, bearing members 28, 29 and 30 respectively, all in alinenient transversely of the line of draft of. the machine.

Extending through the trunk or back bone 1 ot the tractor is the usual drive sha-ft 31, having near its rear end, a worm the terminal of the shaft being mounted in a bearing 33 formed in the lower portion of the ring or housing 2.

Located directly over the worin unl iu mesh therewith, is a worm wheel 341 con stituting the ring wheel ofthe differential, and bolted or otherwise secured to said ring wheel, is a differential housing member 35, in the form of a concavo-convex shell pio vided with a hub, which is revolvably mounted on the inner endl oi' the left hand axle 86, and which is adapted to revolve in an anti-friction bearing 3"? suitably mounted in the left hand axle housing L1.

rThe axle 36 extends beyond the anti-friction bearing 9 carried at the outer end ot the housing d, and is there equipped with the usual traction wheel 38 and a similar anti-friction bearing 39 is provided at the outer end of the other right hand axle hous-A ing 19, while an inner anti-friction bearing L10 is provided at the inner end of the housing 19 where the saine joins to the wall or `face of the enlargement 23 on the closure plate 20. l

The right hand axle 11 is mounted lo revolve in the bearings 239 and 40, and the inner end ol the same extends into the afore said sleeve 24 while the outer end thereoi' extends beyond the outer bearing 89 and is equipped with a traction wheel l2 similar to the wheel 3S.

Secured to the right hand side of the ring wheel 34 is a concave-convex shell or housing 43 which, together with the member S5 form a complete housing for differential gearing7 indicated generally by the reference numeral 44:, the said gearing, ineludng the ring 34 comprising a well-known type of differential gearing now in common use.

llt)

rllhe innerv end of the axle 36 is suitably grooved for splining. 'one of the' bevell'ed pinions of the differential ge-aring`,while tl opposite or right handl bevelled pinion of the diiferent-ial -is similarly secured tothe 'liv ing a bearing in an' antifriction device 46 similar to thel opposite bearing 37 and y mounted in the inner, open end of the'afore-A said sleeve 24. y l

The outer or free end ofthe short! shaft is secured to a head or disc 47 having spaced, concentric'ally mounted and" outwardly-extending,lugs 48 to constitute the female member' of a clutch. The outer face of the head or disc 47'lies'adjacent'to the inner Vend of the right hand axle 41, which is suitably grooved, as at 49,' to slidably mount a sleeve 50y constituting the male member of said clutch, and adapted to be moved" into Aand out of engagement with the lugs 48. The sleeve 50 is provided with an annular groove 51 near its outer end, and is' further provided withv a reduced inner end, thus forming aV shoulder which has ropposite seats 52-to receive the ends of the lugs and transmit power from the short shaft 45 to the right hand axle 41, when the clutch members are connected.

The axle 41 is provided with a cireum fer'ential rib 53, and between the latter and the outer end of the slidable collar 50 is interposeda washer 54 to constitute a thrust bearing for said collar, and to retain said axle in place within the housing 19.

Secured to the attaching flange of the right hand differential housing member 43, is an outwardly-extending, taperedcollar 55 which has an annular base flange 56 for the purpose of receiving the fastening bolts, which thus causethe said collar to revolve continuously with the aforesaid ring gear 34, which is ydirectly driven by the worm 32 on the drive .shaft 31. Adjacent to the outer end of the tapered collar 55 is an outstanding annular ange 57, which'is adapt# ed to carry a gear wheelv 5S, the latter having al reduced web 59 ofannular form and suitably, apertured for thev recept-ion( of bolts 60 whieheause'the'gear wheel te rotate' at all' times with the collar. Y 4 f A yoke 61y is mounted1 in"A the lannuiar groove`51 of the slidalolev clutch'sleeve50, andsaid yoke is formedat right'angles-to a longitudinallyQdisposed slide rod '62, which passe-s out' through' a suitable bearing open'- ing inthe end wall: of the enlargementtheouterend ofthe said' slide rod having; a further sliding bearing in` an arm formeld on the axlehousing' 19. An'operatinglever 64, normfally'- extending, upright, Vis"inter inediately' pivoted 'betweenearsL 65 formed ile on the' enla'rgerne-nt'A VE23, andithe lower end of said,- op'e'r'atingfv lever 64 is' bifu'reat'ed: (as

'8O is'a druml shaft' 66 extending entirely across the `machine and" in rear of and above the axlesv 36 and y41, said shaft being held in the bearings by cap plates 67. Mounted on the d'ruriishaft is a straight faced' pinion 66, whieh is` free to slide longitudinally vvthereon but is causedto turn therewith, with;

in the vaforesaid extensionl andv cap or cover 16 `by awspline 69.` The pinion 68 1s provided with' a. hub having an annular groove 70, in which is mounted a shifting yoke 71"'fornied at theend of a slide rod 72 arranged above the shaft 66 and extending parallel thereto, through thewall of the extension 13 to a point over the intermediate supporting' arm' 26, wherel it is provided with a. fork 73 for pivotal engagement with the free end lof a swinging crank arm 74, mounted onl a' rock shaft 7 5 extending longitudinally of the'l machine Vand located over the axle 36 and the drum shaft 66.v The rocklshaft'75 has its rear end'mounted for rotation in an upstanding lug or arm 76 formed on the intermediate cap plate 67, whilerythe front end of said rock shaft is mounted for rotation in a similar' arm 77v carried by` the front portion ofV the attaching flange of the lefthand axle housing 4, An inclined; operatingflever 78 is suitably secured to the front portion of the rockshaft by means' of which the latter maybe rocked to slide the pinion 66; means' of the yoke 71, red'72'and crank 7 4, inter-or out of meshing relation' with the' aforesaid gear wheel 56, for tliepurpose of diverting the power to the ldrum shaft 66 at any time, either when tlie`axles36 and 4'1 are being driven or when the' saine arel stationary;

Between the left hand supporting arm 25 and the intermediate' arm 263, a drum 79 is mounted'A on the shaft'` 66; the same being suitably keyed "or splinedi toI rotate therewith,

and the sai d' drum has side flanges SO'which reach relatively close to the left hand axle the, aforesaid`l tlattenedor straight portion 7 forming, ample spacel for the same. Adjacent to the outer flange 80, theV drum is equipped with a suitable sfrn'oelret'wheell 81 which Vmay Vbe utilized, when desired", for ving'fa chain. for transmitting power to ditl'e'rentkinds of' machines' Y lThe'" d'rum`shaft further carries abra'ke drzuni' S2, of lstilostantially the'same' diameter lill) as the flanges of the winding drum, and suitably leyed to the shaft between the outer or right hand supportinOv arm 27 and the housing oiI the gear wheel 58 and pinion 68, and surrounding the major portion of said brake drum is a brake band 83, to one end ot which is attached a re-int'orcing plate S4 having one end termed at right angles :tor the reception ot' an adjustable bolt 85, the tree end ot which is termed into an eye 'or pivotal connection between spaced arms 86 carried by a collar 87, the latter forming part ot an operating lever 8S. rlhe collar 87 is pivotally mounted on a pin 89 mounted in opposite ears 90 which are supported on top of the right axle housing lll. The handle 88 extends upwardly and Vnormally inclines forwardly so as to be readily grasped by the right hand ot the operator, whose seat (not sho is located above the ccntral portion ot the urnin shalt, and tl clutch operating handle or lever 64e is located adjacent to the lever 88 so that it too may be readily grasped by the saine hand, while the gear shitting lever 78 is correspondingly located for use by the lett hand oil the operator, and all of said handles or levers may be easily operated by an operator standing on the ground. v

The intermediate portion ol' the brali band 83 is supported by an arm 9i which does not, however, interfere with the application said band by the lever 88 tor the reason that the supporting means carried by said arm Sl is cushioned, and the opposite, 'ti-ce end ol the brake band 83 is connected to a bracket 92, which is, in turn, supported by an arm extending rearwardly from the axle housing 19. (See Figure l.)

From the foregoing it will be seen that one of the divided, separate axles of the above mentioned patent has been eliminated in the present application. By shift-ing the upper or handle end of the lever G4. to the right (assuming that the operator is in the drivers scat), the yoke 6l will torce the slidable sleeve 50 in between the lugs 48, which will lit into the notches r seats 52 and thus locl: the disc 4:7 to the axle Lll, when both axles are coupled to the dil'lferential. It the motor be running. the power from the drive shaft 3]., through the worin 32, will turn the ring wheel 3a in the ,desired direction of rotation, either to drive the vehicle forwardly r rearwardly. The spider gears within the housing members and i3 and constituting part of the usual diiterential gearing, serve in the usual manner to leclt the ievelled pinions at the inner ends of the axle 36 and the short shaft 45 respectively, so that direct and equal power is applied to each ot the traction wheels and the machine is moved in the desired direction. At this time, i'l so desired, the drum shaft may also be rotated and the Lees-race drum caused to wind up a cable, as, for instance, when it becomes necessary for the tractor to pull itselt out of' the mud, or when otherwise stalled, for as long as the motor is running and the ring wheel is being revolved, the collar and the gear 58 are also revolving and it is only necessary to aide the pinion 68 into mesh with said gear wheel 58, by means ot the hand lever 7S, to accomplish this purpose. I

When it is desired to usethe winding drum in handling oil well tools or casings, or in other uses,`where it is necessary it'or the machine to stand stationary, the right hand axle All may be disconnected by shitting the hand lever 64 to remove the collar 50 from the lugs 418, when both axles 36 and il will cease to revolve, but thegear ring 34 will continue, together with the collar 55, gear 58 and the pinion 68, it in mesh, to drive the drinn. At this time the bevelled pinion on the inner end ot' the axle 36, being stationary, causes the spider gears oi the differential to travel about the same, since the spindles ot said spider gears are car 1ied by the said ring. As the spider gears thus travel, they are rotated about their individual axes and the rotative movement is imparted on the other side to the bevelled pinion on the inner end oit the short shalt 45 and the latter is rotated, at an increased rate of speed, and carrying the clutch member 47-/l8 therewith, but since the latter is now disconnected from the axle 4:1, the latter also is tree to remain stationary.

lt is believed that the numerous advantages ot the present invention will be understood and appreciated, and that the same provides a simple, cheaply-manufactured and strong and eiiic'ient means for easy attachment to motor vehicles having separate drive axles, especially to tractors, to render the saine capable ot performinghoisting as well as hauling or pulling.
